### `nrf-recover`
Some nRF52840 devices, specially older revisions, may have parts of their Flash memory locked. To unlock the memory use the [`nrf-recover`](https://crates.io/crates/nrf-recover) tool.
This is only relevant to the nRF52840 Development Kit. First connect the nRF52840 DK to your PC using micro-USB J2 (as done before) then run the following commands:
``` console
$ cargo install nrf-recover
$ nrf-recover -y
Starting mass erase...
Mass erase completed, chip unlocked
```

flash write protection is enabled in the device. To disable it use the `nrf-recover` tool. Instructions can be found in the [`nrf-recover` section of the Installation Instructions].
Ensure that you've installed version 0.10 or higher of `cargo-flash` and `cargo-embed`
